been submitted for this stock tank to be left as a permanent impoundment.
Stock Tank T 3 was holding water but was not discharging. Exhibit 13-27 of the permit contains certified as-built
plans for each stock tank. The pond appears to be the proper configuration. All of the proper documentation has
been submitted for this stock tank to be left as a permanent impoundment.
Ponds 006, 009 and 015 were inspected. The configuration of these ponds was checked during the May 14, 2013
inspection. Please see that report for details. These ponds were holding water and discharging at the time of this
inspection. The embankments were stable and vegetated and the primary and emergency spillways were clear and
functional.

The following road areas within the site are under consideration for Phase I Bond Release; Mine Entrance
Road/Routt County Road 53, Oil Well Access Road/Routt County Road 53,Haul Road A,Haul Road J and the
only remaining portion of Haul Road K that has not been Phase I bond released. Along each road the Division
took several measurements to verify the roads were constructed in accordance with the approved configuration in
terms of width and grade. The width of each road was measured with a tape measure and the grade was checked
with an inclinometer. Exhibit No. 20-3 in the permit depicts the approved post mine road profile and
configurations for these roads.
The Oil Well Access Road/Routt County Road 53 appears to have been recently surfaced with crushed rock.
Exhibit No. 13-25.2 depicts the post mine plan and profile for this road. The Division measured with width and
grade of this road at the OW-1 culvert. The road was found to be 25 feet in width and at about a 7%grade. The
Division interpolated the grade where this culvert is located based on Exhibit No. 13-25.2 and found it to be 6.2%.
The slight difference in grade is allowable. The surface of the road was recently graded and maintained. The road
appears to be draining properly and large rills and gullies were not observed along this road.
For Road A,the approved post mine width is 20+/-feet. The Division measured the width and the grade at four
points along this road. One point is about 125 feet east southeast of grade stake 77+00 as depicted on the
approved post mine topography map (Exhibit 20-2). The width of the road at this point was 21 feet and the grade
was about 9%. The Division interpolated the approximate grade of this road based on the Exhibit No. 20-3 road
profile and found it to be about 6.7%. This slight difference in grade is allowable. Another point was collected
about 160 feet east of the 60+00 grade stake. The road was about 21 feet wide and at an 8%grade. The Division
interpolated the grade at this point based on Exhibit No. 20-3 and found it to be about 6.7%. This slight difference
in grade is allowable. Another point was collected where Culvert A-3 is located. The road was 20 feet wide at
this point and at an 8%grade. Based on Exhibit No. 20 31,the grade at this point was 6.1%. This slight difference
in grade is allowable. Another point was collected about 30 feet west of grade stake 15+00. The road was found
to be 21 feet wide and at a 7%grade. The Division interpolated the grade at this point based on Exhibit No. 20 3
and found it to be about 5%. This slight difference in grade is allowable. The surface of the road was recently
graded and maintained. The road appears to be draining properly and no large rills and gullies were observed
